MACHINE F OR BALLING TWINE.

SPECIFICATION forming part of Letters Patent No. 462,984, dated November10, 1891, Application filed 06tober 23,1890. Serial No. 369,078. (Nomodel.)

To all whom it may concern.-

Be it known that I, ANDREW OALVIN MIL- LER, a citizen of the UnitedStates, and a resident of Auburn, in the county of Cayuga and State ofNew York, have invented a new and useful Improvement in Machines forBalling Twine, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification.

My invention relates to certain improvements upon the machine forballing cord or twine described in my patent, No. 443,103, datedDecember 23, 1890, and more particularly to the construction of thecord-guide arm; to the arrangement of means for controlling themovements of said arm and for changing the direction of movement; to themeans for automatically throwing the machine out of action, and to themeans for stopping and starting the machine, the construction andarrangement of the cylinder and heads of the mandrel, and to certaindetails of construction and arrangement of parts of the machine, all ashereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is I a plan View of a machineembracing my improvements. Fig. ifis an end elevation, partly insection, showing the right-hand (see Fig. 1) or drive-wheel end of themachine. Fig. 3 is a vertical longitudinal section showing thecord-guide arm in side elevation; Fig. 4, a left-hand side elevation;and Fig. 5 represents a transverse vertical section through the cordguide arm near the pivoted end thereof,

showing a portion of the rack-bar and the pawls engaging therewith inelevation.

A indicates the main frame; A, a pivoted portion of the upper left-handside bar thereof for facilitating the removal and replacing of themandrel; B, the main driving-shaft of the machine carrying the mandrel;C, the counter or power shaft carrying a band-pulley 0 connected by abelt 0 with a pulleyB on the shaft B for driving the latter and actuatedby the belt O from any suitable motor. The band-pulley B carries twoband-pulleys I) and b, one on each side, fast either on thedriving-pulley B or on its shaft adjacent to said pulley, as preferred,and connected by belts b I), one straight and the other crossed,with

either of the pulleys cZ-aud cl. central peripheral groove, with whichthe band-pulleys cl and cl mounted loosely on the shaft D, which,between its central and outer left-hand hearings on the frame A, isscrewthreaded and actuates the cord-guide arm E, pivoted through itsinternally-screw-threaded sleeve on said shaft. The pulleys d and d, asstated, are loose on the shaft D and are rotated continuously inopposite directions thereon by the belts and b They are provided ontheir inner adjacent faces each with a socket or clutch face or pin, andbetween these is a sliding clutch-sleeve F, feathered to the shaft fordriving it when engaged with This has a arms of a pivoted shifting-forkF engage for sliding the sleeve endwise on the shaft D. It

is provided on each end with a clutch face or pin f orf, adapting it toengage the adjacent faces of the pulley d or d, as desired.

The fork F is pivoted at one end to a bracket or arm a on the frame andpasses through a slot or fork in the inner or righthand end of arack-bar G. It is provided on its sides with flat springs f andffastened t0 the fork F near its pivoted end, and. also adapted to slidelongitudinally in suitable slots or ways at a a. in the frame.

The cord-guide arm is made in two parts E, indicating the part or endthereof connected by a threaded sleeve with the screwshaft D, andprovided above said shaft with a cordguiding loop or eye 6, throughwhich the cord passes outward to the pivoted and swinging end of the armindicated at E. The part E at a point about centrally of its length isprovided with an upright transverse slot 6, curved in an arc of a circleof which the shaft D is the center, and through which the rack-bar Gpasses, as shown. it and h are pawls pivoted within the slot 6 andhaving heel-extensions, with which set-screws h and 7L3, passing throughthe upper and lower end walls of the slot, engage for effecting theadjustment of the pawls, as desired. The forward or swinging end of thepart E is made in the form of a stud-shaft e and the end of the part E,connecting therewith, has a cylindrical socket or sleeve fitting andpermitting therocking of the part E on said shaft. The stud or shaft (2has athrough-pin 6 near its outer end, the ends of which pass throughslots 6 in the sleeve 6 and serve to hold the sleeve in place and limitthe rocking movement of the part E. The inner or heel end of the part Ehas a laterally-projecting arm I formed on it, to which one end of aspring '0' is connected, the other end of the spring being connected tothe outer end of the part E,

the tension of said spring serving to hold the arm I down with theforked outer end of the part E and the cordguide pulleys j and j thereinin the inclined position shown in Fig. ,1, in which it is best adaptedto lay the cord in inclined layers on the mandrel.

K indicates a bail pivoted at its ends in brackets a a on the frame andresting on the cord w in front of the guide-eye e, for a purpose thatwill appear.

L is an upright lever pivoted on the stand ard-bracket L on the outer orleft-hand end of the frame and provided on one side near its upperswinging end with laterally-projecting spur Z, with which a pawl-lever Lengages for locking the lever L inoperative position.

Thelever L has one end of cord mconnected with it near its upperswinging end, said cord extending forward 'over a guiding-sheave m nearthe outer or left-hand front upper corner of the machine-frame, thenceobliquely down- Ward and across the machine to a guidingsheave m on thelower right-hand side of the side frame, thence up to the forward end ofthe horizontal arm of a bell-crank M, pivoted at its elbow in a suitablependent bracket N, attached to the upper frame-bar. The other end of thebell-crank M carries a pulley M, which by the tension on the cord m ispressed againstthe driving-belt O and serves to take up any slacktherein and to give it thetension necessary for causing it to drive theband-pulley B shaft B, and the ball-winding machinery connectedtherewith. When from any cause the lever L is released from thelatch-lever L the weight of the pulley M causes it to swing away fromthe belt 0, relieving the tension thereon and giving slack enough topermit it toslip and so stop the operation ofthe shaft B and the partsactuated therefrom. The forward arm Z of the lever L is connected by acord is with the bailK, resting on the cord 00, and which by its tensionserves to uphold the bail with the latch-lever L engaging and holding upthe lever L. comes broken, the bail K drops by its own gravity and,operating through the cord k on the lever L releases the lever, and thelatter If the cord as from any cause bethrough the cord in allows thetension-pulley M to drop away from the belt 0 and so stops the machineuntil the broken ends of the cord at are reunited and the lever Lrestored to operative position. Where a break occurs, as explained, theforward arm of the bellcrauk lever M flies upward and strikes aspring-arm O, fastened at one end to the frame and carrying at its otherend a hammer O, which is thereby thrown into contact with a bell P,secured to a frame upright, as shown, thereby giving notice of thebreakage to the attendant. The latch-lever L can of course be disengagedfrom the lever L- by hand and the operation of the machine stopped bythe attendant whenever desired.

The spool on which the cord is wound i composed of the tapering mandrelR, the inner disk or head R fastened by a pin r to the main shaft B, andthe outer disk'or head R, having a tapering socket in the inner end ofits hub, matching the tapering outer end of the mandrel, which, togetherwith the head R, is held in place on the shaft B by awedge or key 19passing through the shaft and holding the mandrel engaged witha pin 1)in the shaft B at the inner end of the mandrel, as shown in Fig. 1.

Just outside the socket in the head R for .the inner end of the mandrelB said head is The outer swinging end of the cord-arm is forked, asstated, and carries two grooved sheaves j and j for guiding the cord,which passes over the inner or first sheavej and under'the outer sheavej to the mandrel.

In starting to wind a ball the end of the cord is secured to the clamp rand the machine is started, with the cord-arm resting in close proximitywith the head R and against the stop 9 and with the pawl h engaging atooth of the rack-bar G. Under this arrangement it will be seen that thecord-arm can only move outward or away from the head R just far enoughto cause the pawl h, acting through the bar G and its connections withthe shifting clutch, to reverse the movement of the cord-arm, when thelatter immediately moves inward again and acts through the stop g on thebar G to again reverse the movement of the cord-arm by the time itreaches the disk R The movement of the cordguide arm is thus limited inone direction by the stop 9 and in the other direction by the pawl h.The cord-guide arm in moving to the right (see Fig. 1) strikes the stopg, and thus moves the rack-bar G to the right, thus reversing thedirection of rotation of the IIO . screw-shaft D, whereupon thecord-guide arm immediately moves in the opposite direction or to theleft, Fig. 1. The cord-guide arm will continue tomove to the left untilthe end carrying the gnidingsheave j passes beyond the layer of corddeposited in its previous movement, when the end of said cord-guide arm,being unsupported by said previous layer of cord,'will descend intocontact with the mandrel or sufficiently near thereto to lower the pawl71, into engagement with the rack-bar, whereby the latteris moved to theleft and the movement of the cord-guide arm reversed. In this way thecord-arm is atfirstmoved back and forth within short limits until atapering base is laid on ,the mandrel, such as is indicated, and thereis cord enough thereon to lift the cord-guide arm and the pawl over thetooth with which it was first engaged, after which it drops intoengagement with the next tooth of the rack, and so on until the desireddiameter of ball or roll at the end adjacent to the disk R is reached,regulated by the adjustment of the pawl h, and the latter comes intoaction on the lower face of the bar G and acts in lieu of the stop g formoving said bar inward in like manner as the pawl h by the descent ofthe arm is made to engage the upper face of the rack-bar for moving itoutward. Just before the cord-arm reaches the outer end of the mandrelin its outward movement and after it fails to fall low enough to causethe pawl h to operate the rack-bar it comes in contact with the stop gand through it operates the rack-bar, shifting-fork, and clutchsleeveuntil the ball or roll is completed in the form described in my formerapplication referred to. When the cord-guide arm gets near the outerlimit of its movement and begins to lay the cord close up to the disk R,the arm I, whichis inclined upward, as shown in Fig. 5, strikes upon theupper face of the standard-bracket L, and being rocked upward thereby asthe cord-arm continues its movement toward the disk R the pivoted part Eof said arm is rocked, bringing the guiding-sheaves j and j intovertical position, adapting them to lay the cord close up to the diskR'. When the cord-arm moves away from the disk, the spring 1 retracts itto its normal position for laying the cord in inclined layers. Thesprings f and f on the shifting-fork I are pressed against or toward thefork on that side toward which the rackbar moves in the first endwisemovement of the bar until by its tension it helps to release theclutch-sleeve from its driving-wheel on one side and to throw it intoengagement with that on the other side.

Having now described my improvement, I claim as'new- 1. The divided ortwo-part cord-guide arm having its inner or heel end pivoted to and incombination with its actuating-shaft and having its outer end pivoted tosaid inner end to rock on its longitudinal axis and the arm and springfor holding said pivoted outer part in its normal working position,substantially as described.

2. The divided cord-guide arm having its outer part pivoted to, itsinner part, as described, and carrying the grooved cord-guiding sheaves,and the arm and spring attached to said outer part for adjusting itautomatically relatively to the inner part, substantially as described.

3. The combination of the cord-guide arm, the screw-shaft for actuatingsaid arm, the driving-wheels on said shaft rotating in op-' positedirections, the sliding clutch-sleeve for engaging said wheels with theshaft, the sliding rack-bar and the shifting-fork for operating saidclutch-sleeve, and the pawls on the cord-arm for engaging and actuatingsaid rack-bar, substantially as described.

4. The combination, with the cord-guideactuating shaft, of the pulleys,for actuating it mount-ed loosely and rotating in opposite directions onsaid shaft, the interposed clutchsleeve feathered to and sliding on saidshaft, the shifting-fork engaging said sleeve, the springs f and f forassisting said shiftingfork, the rack-bar for actuating said springs,and the cord-guide arm pivoted on said shaft and carrying pawls forengaging and actuating said rack-bar, substantially as described.

5; The combination, in a machine for balling cord or twine, of the maindriving-shaft B, the band-pulley B thereon, the pulley (J and belt 0 fordriving said shaft and pulley, the tension-pulley located at a pointintermediate the pulleys B' and C the bell-crank or swinging leverpivoted to the frame and carrying said tension-pulley, the cord m, leverL, and the latch-lever or pawl L for holding the tension in operativeposition, and the bail connected to said latch-lever and operatingsubstantially as described.

6. The combination of the pulleys B and C the driving belt therefor, thetensionpulley and its supporting bell-crank lever, the cord, lever andlatch-lever for holding said tension-pulley lever in operative position,the bail connected to said latch-lever for releasing it, and the alarmarranged and adapted to be operated when the latch is released, in themanner substantially as described.

-7. In a balling-machine, the tapering mandrel R, on which the cord iswound, the disk or head R keyed to and in combination with theactuating-shaft, said disk or head having the eye or perforation andclamp e -for engaging the end of the cord, the outer head R and the key19 and the pin b for. connecting the mandrel and outer head R with theshaft B, all substantially as described.

In testimony whereof I have hereunto set my hand this 18th day ofOctober, A. D. 1800.
